The invention provides a portable testing device of electric automobile charging equipment. The portable testing device comprises a box body, a battery charging base, cables, conversion terminals, a test circuit air switch KK1, a control guiding air switch KK2, a control unit, a man-machine interaction unit and a data acquisition unit, wherein the battery charging base, the cables, the conversion terminals, the test circuit air switch KK1, the control guiding air switch KK2, the control unit, the man-machine interaction unit and the data acquisition unit are arranged inside the box body. A charging plug of tested charging equipment is connected with the battery charging base, and adjustable loads are connected with the conversion terminals. The battery charging base and the conversion terminals are connected through the cables. The test circuit air switch comprises two air switches, wherein one air switch is connected with a connection terminal DC+ of the battery charging base and a corresponding conversion terminal, and the other air switch is connected with a connection terminal DC- of the battery charging base and a corresponding conversion terminal. The control guiding air switch is an air switch which is connected with a connection terminal S+ and a connection terminal S- of the battery charging base. When the testing device is used for testing the charging equipment, the charging equipment is directly connected with the outside through the charging plug arranged on the charging equipment self, and a plurality of connection terminals included in the charging plug do not need to be connected with the outside respectively.
